Nice job and pics. Cann't tell just where the throttle shaft is located. Will it be a straight shot aft to firewall or will it necessiate a bell crank setup?
I try to open adapter like yours up to the full ID of the gasket just to smooth the flow. (Also less metal = less weight

)
I'll have to use a bellcrank of some kind. Don't know where yet, until I get my mounts.
I would have liked to open the adapter up, but as you notice on the case, it has a rectangular hole. If I was to open to the full diameter as the carb, it would cut into my pulse hole, and that just wouldn't work. It's about as wide as I dare go.
